It’s a good try at showing why the US Gardasil vaccine is pretty safe, whatever your risk profile. I particularly liked the lightning to ignition of nightwear axis. That said, the brain is so bad at sizing the area of bubbles, that I think the overall verdict on the diagrams should be that they fail. So they must really be political / gee whiz rather than helpful infographics. Shame, because I’m sure they would work on people, but for all the wrong reasons.
